When the first supporting legs 111 and the second supporting legs 112 of the two supporting members 11 are moved in such a way that bottom ends of the first supporting legs 111 and the second supporting legs 112 are moved away from each other, on one hand, the first holding bracket 131 rotates with respect to the first supporting legs 111, the second holding bracket 132 rotates with respect to the second supporting legs 112; and on the other hand, the first holding bracket 131 and the second holding bracket 132 are rotated with respect to each other, so that the first holding bracket 131 and the second holding bracket 132 tend to be horizontal. When the first holding bracket 131 and the second holding bracket 132 are horizontal, the rack body 10 is unfolded and is in an unfolded state.

When the first supporting legs 111 and the second supporting legs 112 of the two supporting members 11 are moved in such a way that the bottom ends of the first supporting legs 111 and the second supporting legs 112 are moved toward to each other, on one hand, the first holding bracket 131 rotates with respect to the first supporting leg 111, the second holding bracket 132 rotates with respect to the second supporting legs 112, and one the other hand, the first holding bracket 131 and the second holding bracket 132 are rotated with respect to each other, so that the first holding bracket 131 and the second holding bracket 132 tend to be overlapped with each other. When the first holding bracket 131 and the second holding bracket 132 are stacked, the rack body 10 is folded to be in a folded state.

Preferably, when the first holding bracket 131 and the second holding bracket 132 are horizontal, the pivot mechanism 133 can lock the first holding bracket 131 and the second holding bracket 132, so as to ensure that the rack body 10 is reliably retained in the unfolded state.

Specifically, the pivot mechanism 133 comprises a pivot element 1331 and a locking element 1332, wherein the pivot element 1331 has a pivot space 13311 and two limiting grooves 13312 which are respectively communicated with the pivot space 13311 at two opposite sides of the pivot element 1331, wherein two opposite end portions of the locking element 1332 are respectively slidably installed in the two limiting grooves 13312 of the pivot element 1331, so that a middle of the locking element 1332 is located in the pivot space 13311 of the pivot element 1331.

Referring to FIGS. 19 to 27 of the drawings, a bathtub according to another alternative mode of the above preferred embodiment of the present invention is illustrated. In this embodiment, the structure for connecting the edge 220 of the bathtub side wall 22 of the bathtub 20 with the top supporting arm 11 is illustrated. Accordingly, the present invention provides a bathtub assembly 200 which comprises the bathtub 20 and two brackets 120 which are embodied as the shaping bracket 122 and the adjusting bracket 123, the edge 220 of the bathtub side wall 22 is mounted to the two brackets 120.

More specifically, the edge 220 of the bathtub side wall 22 comprises an edge sleeve 221 and two fixing ribs 222, the edge sleeve 221 of the bathtub side wall 22 has two mounting holes 2211 and two retaining channels 2212, each mounting hole 2211 is communicated to the corresponding retaining channel 2212, the edge 220 of the bathtub side wall 22 comprises two fixing ribs 222 which are respectively inserted into the two retaining channels 2212 through the two mounting holes 2211, so that the two fixing ribs 222 are respectively retained in the two retaining channels 2212.

Referring to FIGS. 19 to 25 of the drawings, the bathtub assembly 200 comprises two brackets 120, each of the bracket 120 comprises a rod body 1201 having a fixing cavity 1202 and a slot 1203 extended along a length of the rod body 1201 and communicated to the fixing cavity 1202.

As shown in FIGS. 20 to 25 of the drawings, each rod body 1201 is sleeved on the edge sleeve 221 of the bathtub side wall 22 through a position corresponding to the mounting hole 2211 of the edge sleeve 221, so that the edge 220 of the bathtub side wall 22 comprising the two fixing ribs 312 and the edge sleeve 221 are respectively received and retained in the fixing cavities 1202 of the two rod bodies 1201 of the two brackets 120.

Accordingly, the rack body 10 rack body 10 is a rigid frame that is made of a material selected from the group consisting of wood, metal, metal alloy, and plastic. Metal of the material of the rack body 10 rack body 10 may be Iron, Copper, or Aluminium. The bathtub 20 of the bathtub assembly 200 is preferably a flexible body that is made of a flexible water-proof material such as PE (Polyethylene), PVC (Polyvinyl Chloride), PP (Polypropylene) and TPU (Thermoplastic Urethane). Accordingly, the flexible bathtub 20 is constructed to be easy to be folded up with a folding of the rack body 10 and unfolded with an unfolding of the rack body 10, when the rack body 10 is unfolded, the rack body 10 is supported in the unfolded mode by the pivot mechanism 133 to provide a rigid support to the bathtub 20, and the pivot mechanism 133 is able to be operated to release the rigid support of the rack body 10 when the rack body 10 is operated from the unfolded state to the folded state.

The two brackets 120 can be made of rigid material such as metal, metal alloy, and plastic. The two fixing ribs 222 can be flexible rods that allow each fixing rib 222 to pass through the corresponding curved retaining channel 2212 which may have a semicircle shape. When the two fixing ribs 222 are respectively retained in the two retaining channels 2212 of the edge sleeve 221, the material of the edge sleeve 221 is sandwiched between the inner surface around the fixing cavity 1202 of the rod body 1201 of each bracket 120 and the fixing ribs 222, so that the edge sleeve 221 of the edge 220 of the bathtub side wall 22 is firmly retained and mounted by the two brackets 120. The shape and size of the fixing ribs 222 are respectively matched with the fixing cavities 1202 of the rod bodies 1201 of the two brackets 120, such as that the fixing ribs 222 are engaged with the corresponding two fixing cavities 1202 of the rod bodies 1201 of the two brackets 120 by a snap-fit engaging manner or an interference fit engaging manner, so as to prevent the fixing ribs 222 from slipping out of the fixing cavities 1202.

As an example, the two brackets 120 can be made of Aluminium, and each of the rod body 1201 is an aluminium rod. The two brackets 120 thus can provide a relatively rigid support to the bathtub 20 and the two brackets 120 define a top opening 26 of the bathtub assembly 200, the top opening 26 is also defined and surrounded by the bathtub side wall 22 of the bathtub 20. Since the two brackets 1201 are made of rigid material, the shape of the top opening 26 of the bathtub assembly 200 is maintained. The engagement between the brackets 120 and the edge 220 comprising the fixing ribs 222 and the edge sleeve 221 enables that the edge 220 has a relatively flat surface and the bathtub side wall 22 also has a flat surface that is not easy to form a wrinkle surface, so that the aesthetic appearance of the bathtub assembly 200 is further enhanced.

In addition, the engagement between the two brackets 120 and the edge 220 comprising the fixing ribs 222 and the edge sleeve 221 also enables that the edge 220 of the bathtub 20 is detachably mounted to the two brackets 120 so that the bathtub 20 can be easy to be detached from the two brackets 120 for cleaning.

Accordingly, the top side of the bathtub assembly 200 is arranged with the two brackets 120, so that the aesthetic appearance of the bathtub assembly 200 is enhanced. In other alternative modes, the two brackets 120 may be rods that can be deformed and may be inserted into the edge sleeve 221, however, the structural strength of the bathtub assembly 200 may be relatively weak and the shape of the top opening 26 of the bathtub assembly 200 may not be guaranteed. Two rigid brackets 120 are not suitable for being directly inserted into the retaining channels 2212 through the mounting holes 2211, since the operation is difficult and the surface of the bathtub side wall 22 is easy to be corrugated. Alternatively, the two brackets 120 may be rigid rods that are placed between the two layers of the material of the edge sleeve 221 and then the two layers of the material of the edge sleeve 221 are sewed with each other for retaining the two brackets 120 within the edge 220. However, this configuration will result in that the surface of the edge 220 is not flat because of the additional sewing process, and the manufacturing procedure is relatively complicated, and also the bathtub 20 is fixed to the two brackets 120 can not be detached from the two brackets 120 for cleaning.

In other words, the brackets 120 can be coupled with the edge 220 of the bathtub side wall 22 by any suitable manners, but it is preferred that the two brackets 120 are respectively engaged with the edge 220 by means of the fixing ribs 222 and the edge sleeve 221. The edge sleeve 221 is not required to be formed with a mounting slot at a top side thereof, so that the top surface of the edge sleeve 221 is flat.

In this embodiment, each of the two brackets 1201 is formed with a U-shape, and the two mounting ends 1204 of the rod bodies 1201 of the two brackets 120 are spaced with each other. Accordingly, the edge 220 of the bathtub side wall 22 define two central foldable portions 223 at two opposite sides thereof that are not received in the fixing cavities 1202 of the rod bodies 1201 of the two brackets 120, so that when the two brackets 120 are folded and overlapped with each other, the two central foldable portions 223 of the edge 220 of the bathtub side wall 22 of the bathtub 20 is folded to allow the entire bathtub 20 to be folded.

As shown in FIG. 26 and FIG. 27 of the drawings, the two brackets 120 are pivotally mounted to the two connecting elements 121, so that the two brackets 120 are pivotally mounted with the two connecting elements 121 at positions corresponding to the central foldable portions 223 of the edge 220 of the bathtub side wall 22 of the bathtub 20, so that when the two brackets 120 are folded and overlapped with each other, the two central foldable portion 223 of the edge 220 of the bathtub side wall 22 of the bathtub 20 is folded to allow the entire bathtub 20 to be folded. Each of the two central foldable portions 223 also may be retained in the connecting element 121 so as to be hidden in the corresponding connecting element 121.
